SWI VEL VALVE Filed March 12, 1929 2 Sheets-Sheet 2 lT/PU GOLOG IN INVENTOR 4-7 DUM 2m. @KWSRNEY Patented Feb. 24, 1931 DUMITRU GOLOGA'N, OF NEWARK, NEW JERSEY SWIVEL VALVE Application filed March 12, 1929. Serial No. 346,377.

This invention relates, generally, to iniprovements in radiatorvalves; and the invention has reference, more particularly, to an improved radiator valve which is not only 6Q manually operable to regulate the supply of heating fluid furnished to a radiator, but which is constructed so as to permit turning -movement of the radiator relative to the source of heat supply, whereby thorough .10 cleansing, painting, etc., of the radiator and adjacent room surfaces is made possible.

7 Heretofore when it was desired to have a radiator turnable with respect to its supply pipe, it has been the practice to employ hollow steam packed pivot joint attached to the supply pipe to permit the turning movement of the radiator, and to obtain heat regulation, aradiator control valve was inserted between such-joint and the radiator. Such arrangement of pivot joint and radiator valve in series necessitates the placing of the radiator at an objectionablylarge distance from the supply pipe and at the saine-time results in the radiator having an unattractive appear ance. i r It is the principal object of the present invention to provide a novel swivel valve which not only serves to regulate the supply of-the heating fluid to the radiator, but which is constructed so as to enable turning movement of the radiator with respect to its supply pipe. 1

' Also, the novel swivel valve of this invention provides an attractive, unitary and compactstructure, which is very similar in {11f pearance tothe ordinary radiator valve, but

which is nevertheless adapted to permit turw ing movement of the radiator with respect to its supply pipe.

Other objects of this invention, not at this time more particularly enumerated, will be clearly understood from the following detailed description of the same. Y

The invention-is clearly illustrated inthe accompanying drawings, in which V Fig. 1 is a view in front elevation ofa movable radiator equipped with the novel swivel valve of this invention; 7

' Fig. 2 is a view taken along line 2 -2 of Fig. 1 but illustrating the radiator swung outwardly, from its normal position adjacenta wall;

Flg. 3 is a vertical sectional View of the novel swivel valve ofthis invention;

Fig. 4 is a plan view with parts broken away of the valve shown in Fig. 3; Fig. 5 is a plan View ofawasher with integral key employed in the valveof this inventlon; Y Fig. 6 is a plan view 'of a helical spring also employed in-the valve'of this invention.

Similar characters of reference are employed in, all of the hereinabovedescribed views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference character 1 desig nates a radiator normally positioned adjacent and in substantially parallel relation to a wall 2. Radiator 1 is adapted to be swung outwardly about the stationary steam or hot water supply pipe 3oas an axis. Radiatorl is preferably provided with rollers 4 and 5.

to enable the easy movement of this radiator over the floor 6. Two such rollers 4 are used to support the free end of theradiator, while a single roller 5 is preferably used to support the end 'of the radiator adjacent the pipe 3. a i

The bearing brackets 7 for rollers 4 are provided with upturned fingers 8' which are adapted to. be pressed into frictional engage.-

"ment with the feet 9 of the radiator 1. The

bearing bracket 11forroller5 is adapted to extend between two lof'the feet 9 of the radiator, and this bearing bracket also has upwardly extending fingers 12 for frictionally engaging the feet 9. The construotionof the bearing brackets 7 and 11 enables the ready mounting of rollers 4: and 5-011 the feet of any radiator, since these bearing brackets and rollers are secured to the feet 9 by mere- 5 ly'mounting the bearing brackets on the bottoms of the feet and pressing the retaining fingers against the sides of such feet. 7

The peculiar construction of the novel swivel valve 13 permits the turning of the radiator 1 with respect to pipe 3. Valve 13 comprises a hollowsubstantially cylindrical valve body 14. The internal diameter of this valve .body is reduced at its lower portion forming an inlet opening that is threaded for the greater portion of its length for reception of the supply pipe 3. The. lower exterior portion of valve body 14 is provided with a hex-head 15 that is utilized in threading the valve body 14 on or off of V the upper end of pipe 3.. Valve body 14 is also internally threaded at its upper end portion for the reception'of valve cap 16.

Valve cap 16 is formed with a square head 17 to enable the ready threading of this cap upon the valve body 14. Valve cap 16 is pro vided with an annular flange 18 that is adapted to abut the upper edge of the valve body in overlying relation, thereby forming a fluid tight joint between the cap 16 and the valve body 14. Valve cap 16. is provided with a central, vertically extending aperture 19, that is threaded for the greater part of its length at 26 to receive the threaded central portion 20 of the valve stem21. Valve stem 21 projects upwardly from the valve cap 16 and'h'as a circular handle 22 secured to its upper end as by a screw 23. A stuffing box 24 is threaded upon the top of valve cap 16 and contains packing material 25 for sealing thejoint between the valve stem and; valve. cap. The lower end of valve stem 21 carries a disk valve 27 that cooperates with an annular valve seat 28 formed in the valve body 14 adjoining the inlet opening 10. By manipulating the handle 22, the disk valve 27 may be operated to either open or close the inlet opening 10.

The exteriorsurface of the valve body 14 is upwardly and inwardly tapered and is formed sons to provide two outer inclined bearing surfaces 30 and 31. Bearing surface 30 is provided near thetop of the valve body 14, while bearingsurface 31 is provided near the bottom of this member. These two hearing, surfaces are adapted to cooperate with corresponding inclined bearing surfaces 33 and 34 formed on the interior of a casing 32. These cooperating bearing surfaces are nicely matchedas by lapping so as'to form extremely snug fits while at the same time offering little resistance to turning movement of thecasing with respect to the valve body. Owing to the snugfit of these cooperating bearin surfaces, there is no possibility of fluid within casing 32 escaping between these surfaces to the exterior of the valve 13.

That-portion of the valve body 14that extends between bearing surfaces 30 and 31has its outer surface slightly recessed andis provided with radially extending apertures 35; connecting the interior of'the valve body with an annular recess 36 provided in the casing 32. The annular recess 36 ls'co'nnected i to an outlet opening 38 provided in a laterally extending member 39 of the casing 32. Outlet member 39 is connected by a union pipe joint 40 to the intake pipe 41 of the ra diator 1.. I

Theupper end of casingv 32 carries a fibre washer 44 which surrounds the valve body valve body 14 and is'adapted to bear against the spring 43. This ring is adapted to be adj usted as by a spanner wrench to thereby vary the bearing pressure existing between the cooperating bearing surfaces 30, 33 and 31, 34. The pressure of ring exerted through spring 43, metallic washer 42 and fibre, washer 44 to the casing 32, thereby urging the bearing surfaces 33 and 34 of this easing into intimate contact with'bearing surfaces 30 and 31. The tension of spring'43 as varied by ring 45 determines the desired continuous pressure to be exerted between these cooperating bearing surfaces.

In operation, by adjusting handle 22, the

flow of heating fluid to the radiator 1 is controlled. Owing to the constructionof valve 13 the radiator may readily be turned about its supply pipe 3. While the radiator is being thus turned, the casing 32 turns about the stationary valve body 14 :and the bearing surfaces 33 and'34 turn upon bearing surfaces 30 and 31 respectively. The fibre washer 44 may turn somewhat with the casing, but the metallic washer 42 being keyed to the valve body does not turn so there is no tendency to turn the spring 43 or the ring 45, and hence there is no tendency to loosen the latter ring and relieve the pressure on the cooperating bearing surfaces 30, and 31, 34. The snug fit and peculiar construction of these bearing surfaces eliini nates the necessity of packing between these joints and the exterior of the swivel valve.

lVhile I have described my novel swivel valve'asarranged forv use in connection with valve may be also used in connection with any other apparatus or device, which is desired to be rendered movable about the axis of a fixed supply pipe.
